Application filed April 24, 1923. Serial No. 634,282. I

To all whom, it may concem:

Be it known that I, WILBUR D. HOCKEN- SMITH, a citizen of the United States, and a resident of Irwin, in the county of Westmoreland and the State of Pennsylvania, havemade a new and useful Invention in Mine Cars, of which the following is a specification.

This invention relates to im rovements in mine cars and an object of this invention is to produce a mine car of large capacity for use in low or thin seam mines.

A further object of this invention is to produce a center bumpermine car of relatively large capacity and low overall height which can be discharged by an end dump device such as now commonly used.

This as well as other objects which will readily appear to those skilled in the mine car art I attain by means of the car described in the specification and illustrated in the drawings accompanying and forming part of this ap lication.

In the drawings Figure 1 is a view in side elevation for center bumper mine car embodying this invention, Figure 2 is a top plan view of said car, Fi ure 3 1s a view in end elevation of the same and Figure 4 is a View in section taken on line 4--4 of Figure 2.

The car is providedwith a maincentral floor area formed of wooden planks which run longitudinally of the car and extend beyond the ends thereof to form center bump- "ers. This floor embraces substantially the entire area between the wheels and on each side of the central area and extending a substantial distance beyond the wheels, side floor portions are provided which are slightly inclined to the horizontal and which are provided with covered openings for accommodating the tops of the wheels; I thus provide a highl eflicient composite car.

The central oor of the car is composed of wooden lanks 5, 6 and 7 which extend longitudinally and beyond the ends 8 and 9 to form bumpers 10 and 11 having curved ends as shown in Figure 2. These ends are sheathed with relatively heavy sheet metal as shown at 1212 to provide protection against wear.

Metal angles 13 and 14 are located between planks 5 and 6, and 6 and 7 respectively and extend throughout the lengths of said planks. Planks 5 and 7 are cut away to accommodate flanges 15 :and 16 of the angles and the upright flanges extend flush with the top of the planks. These angles provide efiiclent stilfeners for the center area oor and, confined as they are between the planks they materially assist in preventing the car from buckling due to end impact.

Extending from the central floor to the vertical sides 1717 are metal side floors *18-18. These side floors are slightly inclined to the horizontal and are provided with openings covered by metal caps or housings 19 for covering the tops of the wheels 20 which project above the planes of these side floors.

The center area floor, the side floors and the sides are supported in position upon the axles by and '24.

The side floors 18--18 overlap planks 5 and 7 as shown in Figure 4 for the purpose of stiflening the structure. Bolts 25 secure the planks' o, 6 and 7 the angles 13 and 14 and straps 21, 22, 23 and 24 securely together. A bar 26 bolted to the straps and to the planking extends centrally of the car above the planking substantially to the end of the bumpers 10 and 11. Bar 26 at each end" has a coupler bar 27 riveted thereto as shown at 28.

From the drawings it will be seen that I have produced a center bumper mine car of relatively great capacity and low overall height and smce more than two thirds of each wheel is exposed the car maybe used with the ordinary form of end dump device.

Having thus described my invention what I claim is 1. In a center bumper mine car, a centrally disposed wooden floor divided into longitudinally extending sections, cross braces supporting the floor sections and an gle irons supported on said cross braces, having one flange extending up between adjacent plank sections and extending from one end of the floor to the other.

2. In a center bumper mine car, a central sectional horizontal wooden floor formed of longitudinally extending planks, angle irons extending lengthwise of thefloor between the planks, metal side floor sections extending beyond the car wheels-and intersecting the plane including the tops of the car wheels and provided with housings for the wheels.

3. A mine car having a central horizontal means of metal straps 21, 22, 23,-

floor, side floor sections overlapping said central floor and extending outwardly and upwardly on each side thereof and wheel housings in said side floor sections.

4. A mine car having a central floor extending between the Wheels thereof, and side floor sections extending upwardly from said central portion and intersectin the plane including the tops of the car w ieels.

In testimony whereof, I have hereunto 10 subscribed my name this 6th day of April, 1923.
